【目的】观察卫星神经节周围经皮氙灯照射对自主神经功能的影响。30名健康志愿者作为研究对象。[方法]实验分为两个阶段：1)舒适仰卧位（Xe-LISG），氙灯照射双侧卫星神经节10分钟；2)与Xe-LISG（对照组）相同体位休息10分钟。通过功率谱分析R-R区间和上肢和下肢皮肤温度（UE和LE）得到低频（0.04 ~ 0.15 Hz）功率（LF）和低频与高频（0.15 ~ 0.40 Hz）功率（LF/HF）之比。【结果】虽然对照组前后HF和LF/HF无明显变化，但与对照组相比，Xe-LISG后HF明显升高，LF/HF明显降低。此外，虽然在Xe-LISG期间UE皮肤温度有高于对照组的趋势，但在Xe-LISG期间LE皮肤温度有低于对照组的趋势。【结论】这些结果提示，Xe-LISG抑制交感神经活动，不仅引起UE皮肤血流量增加，而且引起LE皮肤血流量减少。
[Purpose] The purpose of the present study was to investigate the effects of transcutaneous xenon light irradiation around the satellite ganglion on autonomic functions. [Subjects] Thirty healthy volunteers were the subjects. [Methods] The subjects underwent two experimental sessions: 1) 10-minute xenon light irradiation to the bilateral satellite ganglions in a comfortable supine position (Xe-LISG); and 2) 10-minute rest in the same position as Xe-LISG (control). The low frequency (0.04-0.15 Hz) power (LF) and ratio of LF to the high frequency (0.15-0.40 Hz) power (LF/HF) obtained from power spectral analysis of R-R intervals and skin temperatures of the upper and lower extremities (UE and LE) were examined. [Results] Although no significant changes of HF and LF/HF were observed before and after the control, HF after Xe-LISG was significant increased compared with the before Xe-LISG, and LF/HF after Xe-LISG was significantly decreased compared with that before Xe-LISG. Additionally, although the UE skin temperature during Xe-LISG tended to be higher than that during the control, the LE skin temperature during Xe-LISG tended to be lower than that during the control. [Conclusion] These results suggest that Xe-LISG inhibits sympathetic activity and induces not only an increase in the UE skin blood flow, but also a decrease in the LE skin blood flow.
